> I investigated lock contention during concurrent page loading  
> (PageLoader.loadPage).
> There are two main producers of lock contention:
> ComponentInstantiatorSourceImpl and PlasticClassLoader.
> I created a patch for two top issues, see it in attachments.
> There is still issue with PlasticClassLoader. I will report separate issue 
> regarding it.
